The Lowdown
Right then, let’s have a look at what’s on the cards for Jaconé over the next couple of weeks. The water temp here is sitting at 73°F, which is pretty much normal for this time of year, so no surprises there.
The week starts off with a solid pulse of swell that’ll have the banks working. Sunday morning (23 August) sees a 6ft SSW swell pushing in with a 10-second period, and the energy is moderate at 655. The wind is light cross-off from the east, making for clean, workable waves. It’s not a world-beater but a good, honest surf. This holds through Sunday afternoon, still clean with that 6ft SSW groundswell.
Come Monday (24 August), things step up. The morning brings a 8ft S swell at 13 seconds – that’s proper groundswell energy, and you can feel it in the combined energy reading of 1910. Light cross-off wind keeps it clean. This is excellent surf for anyone with a bit of experience, but at 8ft it’s starting to push the limits for beginners. The afternoon jumps to a 10ft S swell at 14 seconds, energy at 2944 – that’s a big, powerful wave. Only for experts. The wind goes cross-shore, so there’ll be a bit of texture but still rideable if you know what you’re doing.
Tuesday (25 August) is still pumping. Morning has an 8ft S swell at 14 seconds (2698 energy), clean with light cross-off wind – another top session for the experienced crew. The afternoon stays clean at 8ft but the breeze picks up to a moderate 12 mph cross-off, still workable.
Wednesday (26 August) morning is a standout. A 5ft S swell with a very long 16-second period, energy at 2557, and proper offshore wind from the ENE at 9 mph. That’s glassy, lined-up, and powerful. The long period means it’ll be better on the point or reef if there’s one around, but if you can find a bank that holds, this will be magic. The afternoon gets bigger again to 8ft S at 15 seconds, but the wind is stronger cross-off, so it’s lumpier.
Thursday (27 August) is consistent. 7ft S swell at 14 seconds in the morning, clean with a light breeze, energy at 2083. The afternoon drops slightly to 7ft but the wind eases to a light cross-off, making for another clean session.
Friday (28 August) sees the swell ease. Morning has a 4ft S swell at 12 seconds, clean with light offshore from the NE. Still fun but not as meaty. The afternoon drops to 4ft and is marginal.
Saturday (29 August) brings a shift. A new 6ft ENE swell at a short 8-second period pushes in, with a light offshore wind. The energy is moderate at 671, but that short period will feel a bit weaker and more windswell-like. Still clean and fun for a grovel.
Sunday (30 August) morning has a 7ft ENE windswell at 9 seconds, clean with offshore wind. The afternoon glass off with southerly wind and 4ft, but it’s small and glassy.
Monday (31 August) morning picks up again with a 7ft ENE swell at 8 seconds, clean. Afternoon goes cross-on and marginal.
From Tuesday (1 September) through Wednesday morning (2 September), it really drops off. Small, weak swells and poor conditions – nothing to write home about. Wednesday afternoon (2 September) gets glassy with a 5ft SSW windswell at 7 seconds, but it’s short period and weak.
Then Thursday (3 September) morning fires up again. An 8ft SSW groundswell at 12 seconds, energy at 1652, with a light offshore wind. That’s a real highlight for the second week – a proper clean, powerful session for experts.
Friday (4 September) morning still has a solid 6ft S swell at 10 seconds with offshore wind, but the breeze is stronger. The rest of the forecast fades into smaller, cleaner but weaker swells. The last few days from 5 September to 7 September are mostly small, clean, but not punchy – good for a longboard or a fish.
Overall, the absolute best session on offer is Wednesday (26 August) morning with that offshore wind, long-period groundswell, and solid size. A close second is Thursday (27 August) morning for its clean consistency, and then Thursday (3 September) morning for the second week. The first week has some big, powerful days that are only for experts, so pick your sessions wisely.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
